Method and system for automatically controlling a following vehicle with a scout vehicle
First Claim
1. A method for automatically controlling at least one following vehicle, the method comprising:
- producing a scout trajectory for a scout vehicle;
guiding the scout vehicle along an actual trajectory, the actual trajectory of the scout vehicle and scout environmental data is captured by scout sensors;
producing a desired trajectory for the following vehicle and following vehicle environmental data are captured by following vehicle sensors;
determining a scout trajectory similarity based on the scout trajectory produced and the captured actual trajectory, reference trajectory data are produced and reference environmental data are produced based on the scout environmental data;
transmitting the reference trajectory data and the reference environmental data to the following vehicle;
determining a trajectory similarity by a trajectory comparison based on the desired trajectory produced and the transmitted reference trajectory data;
determining an environmental data similarity by an environmental data comparison based on the captured following vehicle environmental data and the transmitted reference environmental data, in which case;
in response to the trajectory similarity and/or the environment similarity exceeding a particular threshold value, automatic control of the following vehicle is activated, andin response to the trajectory similarity and/or the environment similarity not exceeding a particular threshold value, a safe driving mode of the following vehicle is activated.

Abstract
A method and system for automatically controlling at least one following vehicle where a scout trajectory is produced for a scout vehicle and the scout vehicle is guided along an actual trajectory, the actual trajectory of the scout vehicle and scout environmental data is captured by scout sensors. A desired trajectory is produced for the following vehicle and following vehicle environmental data are captured by following vehicle sensors. A scout trajectory similarity is determined based on the scout trajectory produced and the captured actual trajectory, reference trajectory data are produced and reference environmental data are produced based on the scout environmental data. The reference trajectory data and the reference environmental data are transmitted to the following vehicle and a trajectory similarity is determined by a trajectory comparison based on the desired trajectory produced and the transmitted reference trajectory data.

12. A system for automatically controlling at least one following vehicle using a scout vehicle, the scout vehicle comprising:
-
a scout journey planner which produces a scout trajectory for the scout vehicle, a scout control device which guides the scout vehicle along an actual trajectory, and scout sensors which capture the actual trajectory of the scout vehicle and scout environmental data; the following vehicle comprising; a following vehicle journey planner which produces a desired trajectory for the following vehicle, following vehicle sensors which capture following vehicle environmental data, and a following vehicle control device which guides the following vehicle along the desired trajectory; wherein a computing unit produces reference trajectory data based on the actual trajectory of the scout vehicle and produces reference environmental data based on the scout environmental data, the reference trajectory data and the reference environmental data are transmitted to the following vehicle, the computing unit is used to determine a trajectory similarity by a trajectory comparison based on the desired trajectory produced and the transmitted reference trajectory data, the computing unit is used to determine an environment similarity by an environmental data comparison based on the captured following vehicle environmental data and the transmitted reference environmental data, and in response to the trajectory similarity and/or the environment similarity not exceeding a particular threshold value, the following vehicle control device activates a safe driving mode of the following vehicle. - View Dependent Claims (13, 14, 15)
